Objective To understand the current medication adherence of the patients suffering from chronic diseases,analyze its relationship with medication convictions and provide a path to improve the medication adherence level of the patients suffering from chronic diseases.Methods A total of 220 patients suffering from hypertension,diabetes,coronary heart disease and other chronic diseases who were admitted to the Chronic Disease Clinic of a grade-A and first-class hospital in Wuhu from October 7 to 13,2019 were randomly selected.The medication adherence report scale(MARS-5)and beliefs about medical questionnaire(BMQ-G)were used to investigate the patients,and the data obtained from the survey were statistically analyzed.Results The patients suffering chronic diseases were poor in medication adherence,with the score of(14.25±3.15)points.Medication adherence was related to gender,age,and educational background(P<0.05),while it was not related to the type of diseases(P>0.05).There was a correlation between the three dimensions of medication convictions(excessive application,beneficial convictions and harmful convictions)and medication adherence(P<0.01).Beneficial convictions and excessive application could exert a significant prediction effect on medication adherence(P<0.01).Conclusion Patients suffering from chronic diseases have a low medication adherence level,and there are obvious differences in gender,age and education;among the medication convictions of the patients suffering from chronic diseases,beneficial conviction predicts medication adherence positively,and excessive application negatively predicts medication adherence.
